Question

1) What is the unit rate for a train that travels 10.5 kilometers in 8 minutes?

O A. 1.75
O B.0.762
C. 84
D. 840

Answer 1

Explanation:

Given that,

Distance, d = 10.5 km = 10500 m

Time, t = 8 minutes = 480 s

We need to find the unit rate of a train motion. The distance divided by time is equal to the speed of the object.

`\text{Rate}=\frac{\text{Distance}}{\text{time}}\\\\=(10500\ m)/(480\ s)\\\\=21.87\ m/s`

So, the unit rate is 21.87 m/s.
