Question

raphael drives to his office which is 75km away from his house what is his speed if it takes him 1 hour and 15 minutes to get to his office

Answer 1

1km\h

Explanation:

like in physics, the calculation of speed is total distance divided by total time, you should do the same in math, and so you do 1 hour (60 minutes) + 15 minutes which gives you 75 minutes, and then you divide 75 km by the time so it should look something like this:

`(75 km)/(75 minutes)` which gives you 1

so raphael is going 1 km\h

Answer 2

`\huge\boxed{\sf v = 60\ km/hr}`

Explanation:

Given:

Distance = S = 75 km

Time = t = 1.25 hours

Required:

Speed = v = ?

Formula:

v = S/t

Solution:

v = 75/1.25

v = 60 km/hr

`\rule[225]{225}{2}`
