A truck left a depot at noon traveling an average speed of 40 km/h .How far from the depot and at what time will it overtake another truck , which left the same depot 2 hours earlier and was traveling 30km/h

at 6.00 p.m. it will overtake and distance will be 6 X40 = 240km/h from the depot

Step-by-step explanation:

Earlier truck is  2 X 30 = 60km/h away from the depot by the time the second truck starts  40km/ h

Net speed of second truck = 40-30 = 10km/ hour

Distance = 60km

Time = Distance / speed = 60/10 = 6 hours

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
