Question

Zach ran an 8K (8 kilometers) race for an Autism Awareness Week fundraising event. Use that information to answer the three problems below.

a) How many meters did Zach run, if 1 kilometer = 1000 meters?

b) The temperature was 10C at the start of the race. Use the formula below to convert that temperature to degrees Fahrenheit.

F = 1.8C + 32

c) It took Zach took 2520 seconds to complete the race. Convert that to minutes, using the conversion 60 seconds = 1 minute.

Review all answer choices before making your decision. Only one of the given choices has all three parts correct. This is a 3-point question, so take your time and work out each part carefully.

Answer 1

Zach ran 8000 meters in the 8K race. The temperature of 10°C at the race start equals 50°F, and the race time of 2520 seconds converts to 42 minutes.

Step-by-step explanation:

Zach participated in an 8K race for Autism Awareness Week, and we are tasked to solve related questions about his run.

a) Conversion from Kilometers to Meters

Zach ran an 8-kilometer race. Since 1 kilometer is equivalent to 1000 meters, we calculate the total distance in meters by multiplying the number of kilometers by 1000:

8 kilometers × 1000 = 8000 meters

b) Temperature Conversion from Celsius to Fahrenheit

The temperature at the start of the race was 10°C. Using the formula F = 1.8C + 32, we can convert this temperature to Fahrenheit:

F = 1.8×10 + 32

= 18 + 32

= 50°F

c) Conversion from Seconds to Minutes

It took Zach 2520 seconds to complete the race. To convert seconds to minutes, we divide the total number of seconds by 60 since there are 60 seconds in a minute:

2520 seconds ÷ 60 = 42 minutes
