Answer:
3.5 hours
Step-by-step explanation:
Given: Distance= 26.2 miles
Speed= 12 km/h
First lets convert the unit of speed from kmh to mph.
Remember, 1 mile= 1.609 km
∴ For speed of 12 km/h= [tex]\frac{12}{1.609}= 7.45\ mph[/tex]
Speed= 7.45 mph
Next, find time taken by Allan to complete a Marathon.
[tex]Time= \frac{Distance}{speed}[/tex]
⇒ Time= [tex]\frac{26.2}{7.45}[/tex]
∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)
∴ Allan took 3.5 hours to complete marathon.
