Answer: 210 km
Step-by-step explanation:
To find the answer, you need to translate the time given into all hours. 20 minutes is 1/3 of an hour so we have 2 and 1/3 hours total. Then all you need to do is multiply that number, 2 and 1/3 hours, by the 90 km/h. You get 210 km total as your answer.
Answer:
210km
Step-by-step explanation:
20min=60/3=⅓ hours.
So the car runs for:
2h+1/3h=(6+1)/3=7/3hours
Distance=speed×time=90m/h×7/3h=210km
