Question

rohit travels by car with the speed of x km/hr for 4 hours and with the speed of y km/hr for 5 hours. Write an expression for total distance traveled by him​

Answer 1

Answer:

d=2x+3y

Step-by-step explanation:

First case :

Speed = x km/hr

Time = 2 hours

Distance = Speed \times TimeSpeed×Time

= 2x2x

Second case :

Speed =y km/hr

Time = 3 hours

Distance = Speed \times TimeSpeed×Time

= 3y3y

Let d be the total distance

So, total distance : d= 2x+3y

Hence the expression for total distance travelled by him : d=2x+3y
