let the required speed =X(km/hr)
speed(km/hr) =50 X
time(min) =90 75
as it is inverse variation
Xx75=50x90
X=50x90 divided by 75
X=60
sothe required speed = 60 km / hr
speed(km/hr) =50 X
time(min) =90 75
as it is inverse variation
Xx75=50x90
X=50x90 divided by 75
X=60
sothe required speed = 60 km / hr

Convert time to hours:
1 hour 30 mins = 1.5 hours
Find the distance:
Distance = Speed x Time
Distance = 50 x 1.5 = 75 km
Find the speed when he is late:
15 mins = 0.25 hour
Time needed = 1.5 - 0.25 = 1.25 hour
Speed = Distance ÷ Time
Speed = 75 ÷ 1.25 = 60 km/h
Answer: The total distance is 75 km and the speed is 60 km/h
