Answer:
Step-by-step explanation:
<h3><u>Formula to be used in the question:</u></h3>- Speed = Distance / Time
= 130 km
<h3><u>Distance for the next 3 hours:</u></h3>Speed = 85 km/h
Time = 3 hours
So,
Distance = Speed × Time
Distance = 85 × 3
Distance = 255 km
So,
<h3><u>Total distance from home to destination:</u></h3>= 130 + 255
= 385 km
<h3><u>Speed on the return journey:</u></h3>Total distance = 385 km
Time = 5 hours
Speed = Distance / Time
Speed = 385 / 5
Speed = 77 km/hr
