Question

Daniel is in a 2-day rally car race.

On day 1, Daniel takes 1 hour and 20 minutes to travel 115 km.

On day 2, Daniel takes 2 hours to travel 175 km.

What is Daniel's average speed over the 2 days.

Worked Solution

Total distance = 115 + 175 = 290 km

Total time = 113+21\dfrac{1}{3} + 2
= 103\dfrac{10}{3} hours

∴\therefore Average speed = distancetime\dfrac{\text{distance}}{\text{time}}
= 290 ÷103\div \dfrac{10}{3}
= 290×310\dfrac{290 \times 3}{10}
= {{{correctAnswer0}}} {{{suffix0}}}
