Question

Jack and Jill like to ride bikes. Jill can ride at a constant speed of 10 miles per hour. Jack can ride at a constant speed of 616 feet per minute. What was Jack's speed in miles per hour? (1 mile = 5280 feet)

Answer 1

Jack's speed of 616 feet per minute is equivalent to approximately 7 miles per hour after converting feet to miles and minutes to hours.

Step-by-step explanation:

The student wants to know Jack's speed in miles per hour when given his speed of 616 feet per minute and the conversion rate of 1 mile equaling 5280 feet.

To convert Jack's speed to miles per hour, we do the following steps:

1. Convert feet per minute to feet per hour by multiplying by 60 (since there are 60 minutes in an hour).
2. Divide the result by 5280 to convert feet to miles.

Step 1: Jack's speed in feet per hour:
616 feet/minute * 60 minutes/hour = 36960 feet/hour

Step 2: Jack's speed in miles per hour:
36960 feet/hour / 5280 feet/mile ≈ 7 miles per hour.
