Question

Marco drove 75 miles in 1 2/3 hours. How many miles can he drive in 1 hour? (SHOW WORK)

Answer 1

45 miles

Explanation:

Marco's average speed is ...

(75 mi)/(5/3 h) = 75·3/5 mi/h = 45 mi/h

Marco's rate of travel is 45 miles in one hour.

Answer 2

He covers 45 miles in one hour

Explanation:

Given,

Distance covered by him = 75 miles,

Time, t =
`1(2)/(3)` hours,

We know that,

`\text{Speed}=\frac{\text{Distance}}{\text{Time}}`

Thus, his speed =
`(75)/(1(2)/(3))`

`=(75)/(5/3)`

`=(75* 3)/(5)`

`=15* 3`

= 45 miles per hour

Hence, he covers 45 miles in one hour.
