Answer to Question #58143 in Physics for Luise

Question

Jio is preparing for his way to school. His house is 30 km away. What time will he be there at school if he leaves his house at 6:30 a.m. and travels at an average speed of 40 km/h?

Answer 1

We can find the time that Jio needs to reach the school from the formula:
t=s/v=(30 km)/(40 km⁄h)=0.75 h=0.75∙60 min=45 min.
Then, Jio will be at school at 6:30 a.m.+45 min=7:15 a.m.
Answer:
Jio will be at school at 7:15 a.m.
