Question

An insect traveled at a speed of 50 yards per hour for 70 minutes. Then it traveled for 18 minutes at twice it's original speed. What is the total number yards this insect traveled?

Answer 1

88 1/3 yards.

Explanation:

For the first 70 minutes:

Distance = speed * time

The time in hours = 1 /1/6 = 7/6 hours so

Distance = 50 * 7/6 = 58 1/3 yards.

For the next 18 minutes it travels at 50 * 2 = 100 yards per hour.

Distance = 100 * 18/60 = 30 yards.

Total distance travelled = 88 1/3 yards.

Answer 2

The answer to your question is The insect traveled 88.3 yd

Explanation:

Data

First travel Second travel

speed = 50 yd/h time = 18 min

time = 70 min speed = 2(50) yd/h

Formula

speed = distance / time

- Solve for distance

distance = speed x time

Process

1.- Calculate the distance travel during the first part

distance = 50 yd/h x 70/60 h

distance = 50 x 1.17

distance = 58.3 yd

2.- Calculate the distance travel during the second part

distance = 100 yd/h x 18/60

distance = 100 x 0.3

distance = 30 yd

3.- Calculate the total distance traveled

distance = 58.3 + 30

= 88.3 yd
