Sagot :
Answer:
1km\h
Step-by-step 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:
[tex]\frac{75 km}{75 minutes}[/tex] which gives you 1
so raphael is going 1 km\h
Answer:
[tex]\huge\boxed{\sf v = 60\ km/hr}[/tex]
Step-by-step 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
