plz answer me fastly its very urgent​

Answer 1

Answer:

Distance=63 km

Time=1.75 hr

Speed=63/1.75=36 km / hr

Answer 2

Hey MATE!!!

GIVEN : Distance = 63 km

Time = 1 hr 45 min ( converting min into hours).

=> 1 + 45/60

=> 1 + 3/4

=> 7/4 hr

$average \: speed \: = \frac{total \: distance}{total \: time} \\ \\ average \: speed \ = \frac{63}{ \frac{7}{4} } = > \frac{63 \times 4}{7} = > \: 36 km{hr}^{ - 1}$

Hence, average speed must be

36 km/hr

Hope it helps
