The distance from Antville to Beetleton is 60 km.

serious [3.7K]

Answer:

i. Time = 2 hours.

ii. Average speed for the whole journey = 25 km/h

Step-by-step explanation:

Distance from Antville to Beetleton = 60 km

Mr. Caterpillar's speed = 30 km/h

Speed = $\frac{distance}{time}$

⇒ time = $\frac{distance}{speed}$

= $\frac{60}{30}$

= 2

time = 2 hours

It would take Mr. Caterpillar 2 hours to travel from Antville to Beetleton at that speed.

On his return journey, his average speed is 20 km/h. Therefore;

average speed for the whole journey = $\frac{30 + 20}{2}$

= $\frac{50}{2}$

= 25

average speed for the whole journey = 25 km/h
