Question

A car travels 23 km in 32 minutes. What is its average speed in km/h? Give your answer rounded to 1 decimal place.

Answer 1

Answer:

first convert 32 minutes to hour

60 minutes = 1 hour

1 min = 1/60 hr

therefore 32 min = 1/60 x32

= 0.53 hour

now in 32 min the car travel 23 km

we can write 0.53 hours instead of writing 32 min

therefore

in 0.53 hour the car travel 23 km

in 1 hour the car will travel 23/0.53 = 43.39 km

the meaning of the word per hour is how much it travels in one hour .

so the speed of the car is 43.39 km in one hour or 43.39 km/ hour
