Question

Harper left his house at 9:15 am. He walked 2.5 miles. If harper returned home at 10:00 am, what was his speed in miles per hour.

Pls help! Due in 30 mins

Answer 1

• Time taken=10:00-9:15=0:45 h=3/4h=0.7h
• Distance=2.5mi

Speed=

`\\ \rm\Rrightarrow Distance/Time`

`\\ \rm\Rrightarrow 2.5/0.7`

`\\ \rm\Rrightarrow 3.5mph`

Answer 2

3.3 miles per hour. this is because speed is equal to distance travelled divided by time taken. so you calculate how many minutes he spent that is from 9:15 to 10:00 . since you are calculating in miles per hour, you convert the minutes to hours and do the working according to the formula
