Question

A cyclist rides her bike at a speed of 40 km per hour. What is the speed in miles per hour? How many miles will the cyclist travel in 5 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers.

Answer 1

1 mile= 1.6 km

therefore:

1km = 0.625miles

To calculate how many miles are in 40 km:

40×0.625miles =25 miles

The cyclist bikes at 25 miles per hour, so in 5 hours she will bike 25x5= 125 miles

She travels 125 miles in 5 hours

Answer 2

125 miles in 5 hours

Explanation:

To convert the speed from kilometers per hour (km/h) to miles per hour (mph), you can use the conversion factor: 1 mile = 1.6 kilometers.

Convert the speed:

Speed in mph = (Speed in km/h) / 1.6

Speed in mph = 40 km/h / 1.6 = 25 mph

So, the speed of the cyclist is 25 miles per hour.

To calculate how many miles the cyclist will travel in 5 hours, you can use the formula:

Distance = Speed × Time

Distance = 25 mph × 5 hours = 125 miles

The cyclist will travel 125 miles in 5 hours
