18. One biker rode at an average speed of 10.1 kilometers per hour. How far did

bikes

he ride in 5 hours?

50.5 km

Step-by-step explanation:

If speed=distance/time, then distance=time*speed.

So we have the time and the speed to find the distance.

We just need to multiply 5 hours and 10.1 km/hour.

distance = (5 hours) (10.1 km/hour)

The time unit cancels and you are just left with the distance unit.

distance=50.5 km

Answer:50.5 km
