Jesse drove 40 miles in 45 minutes if she continues at the same speed how many miles would she drive in 90 minutes

80 miles

Step-by-step explanation:

Speed = distance / time

Speed = 40/45

= 0.89miles/minute

If she continues at this speed, she will cover;

0.89 = distance/ 90

distance = 0.89*90

= 80 miles

40 is the final : )

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
