Step-by-step explanation:
1hr =60 min
40min = 40/60 =2/3hr
speed = displacement/time
speed = 75km/hr
displacement/ 2/3hr = 75km/hr
displacement = 75×2/3 km
= 25×2 = 50km
speed =30km/hr
displacement = 50km
speed = d/t
t = d/speed
t= 50/30 hr
t = 5/3 ×60 min
= 100 min
= 1hr 40min

Answer:
Step-by-step explanation:
ATQ
Speed of the car= 75 km/hr
Distance covered in= 40 min
40 min= 2/3 hr
∵ Distance= speed*time
∴
= 25 * 2
= 50 km/40 min
ATQ
∵ Time= distance/speed
∴ 50/30= 5/3
= 1.6
= 16/10
= 16/10*60
= 16*6
= 96 minutes
= 1 hr 36 minutes
