Complete Question

A car is traveling at speed of 40 meters per second. What is the car's speed in kilometers per hour? How many kilometers will the car travel in 2 hours?. Do not round your answers.

a) What is the car's speed in kilometers per hour?

144km/hr

b) How many kilometers will the car travel in 2 hours

288km/hr

Step-by-step explanation:

Step 1

We convert 40 meters per seconds to kilometers per hour

1 meter per second = 3.6 kilometers per hour

40 meters per second = y kilometers per hour

Cross Multiply

y kilometers per hour × 1 meter per second = 3.6 kilometers per hour × 40 meters per second

y kilometers per hour = 3.6 kilometers per hour × 40 meters per second/ 1 meter per second

= 144 kilometers per hour

Therefore the cars speed in kilometers per hour is 144 kilometers per hour.

Step 2

How many kilometers will the car travel in 2 hours?

If 1 hour = 144 kilometers

2 hours =

Cross Multiply

= 2 hours × 144 kilometers/ 1 hour

= 288 kilometers.

Therefore, the car will travel 288 kilometers in 2 hours.
