Hint:
We have been given a speed value in the unit of miles per hour. We need to convert it to kilometres per hour. We find the relation between mile and kilometer. Then using the unitary system, we convert the value of 60 miles into kilometres. The multiplication value is the solution to the problem.
Complete step by step answer:
We have been given the speed value of 60 miles per hour. We need to convert it in kilometers per hour.
Speed is usually measured by the distance covered in unit time.
For both types of units, the time unit is fixed as an hour. We just need to convert the distance unit from mile to kilometre.
The relation between mile and kilometre is that 1 mile is equal to 1.60934 km.
We have to find a value of 60 miles.
Using the unitary system, we get that 60 miles are equal to $60\times 1.60934=96.56064$ km.
We take the approximate value of 96.56 km.
Therefore, 60 miles per hour is as fast as 96.56 kilometres per hour.
Note:
We need to remember that mile is not part of the metric system but kilometre is. All the units in the metric system are connected with each other by the power of 10. Only if the students remember the relation between miles and kilometers, they can solve this problem. So, 1 mile = 1.60934 km must be kept in mind.
