Question

Rohit travel by car with speed of x km/hr for 2hours and 3hours with the speed of y km/hr .Write the expression for total distance travelled by him

Answer 1

2x+3y.. is answer.....

Answer 2

Answer:

d=2x+3y

Step-by-step explanation:

First case :

Speed = x km/hr

Time = 2 hours

Distance = $Speed \times Time$

               = $2x$

Second case :

Speed =y  km/hr

Time = 3 hours

Distance = $Speed \times Time$

               = $3y$

Let d be the total distance

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

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