We have some couples of angles that are equal
Answer:
2911.5 km/h
Step-by-step explanation:
To tackle this question, you need to work out the average speed of each train and then find the difference.
Note that they want the answer km per hour.
Use the equation speed = distance / time
Paolo's train : 70 km × (35 / 60)
= 24.5 km/h
Monica's train :
For Monica's train you have to work out the time taken.
16 : 15 to 20 : 45 = 4.5 hours
Now subsitute into the speed = distance / time equation.
684km x 4.5 hrs
= 2916 km/s
Now find the difference between the two average speeds.
2916 - 4.5 = 2911.5 km/h
hope this helps :)
