Answer:
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.
