A car drives at a speed of 90km/h for 2 hours and 20 minutes.

How far does the car drives?

210 kilometers

Step-by-step explanation:

First; we are going to divide.

60 (hour in minutes) / 20 mins ... to find out what the excess distance the car went.

Which is 1/3 or 0.3333333 ...

Second; we are going to combine the decimal and the whole number together.

2 hours + 0.333333 ... hours = 2.3333333 ... hours

Finally; we are going to multiply

90 (km/h) * 2.33333333

Which equals ... 210 kilometers!
