please friends help me to solve this question answer

Answer 1

Answer:

15 / 60 = 1/4 hr

Speed = 80 km/hr

Distance = speed x time

= 80 x 1/4

=20km

Speed = 60 km/hr

Distance = speed x time

=60x1/4

=15

20 + 15

= 35

Explanation:

Answer 2

Answer:

$35 \ km/hr$

Explanation:

• The car moves at a speed of $80 \ km/hr$ for $15 \ minutes$ which means that the distance covered will be:

        $distance = speed \times time$

        $distance = 80 \times 0.25$

        $distance = 20 \ km$

• Then, the car moves at a speed of $60 \ km/hr$ for the next $15 \ minutes$ which means that the distance covered will be:

        $distance =$ $speed \times time$

        $distance = 60 \times 0.25$

        $distance = 15 \ km$

• Therefore, the total distance covered will be:

        $20+15 = 35 \ km$

Hence, the total distance covered by the car is $35 \ km$.
