Answer:
1. <u>distance</u><u> </u><u>is</u><u> </u><u>2</u><u>1</u><u>0</u><u>k</u><u>m</u>
<u>2</u><u>.</u><u> </u><u>distance</u><u> </u><u>is</u><u> </u><u>1</u><u>6</u><u>3</u><u>•</u><u>3</u><u>k</u><u>m</u>
Step-by-step explanation:
<h2> <u>QN1</u><u>;</u></h2>
<h2> <u>STEP1</u><u>;</u></h2>
SPEED=DISTANCE÷TIME
90km/h= X ÷ 2 hrs and 20mins
<h2> <u>STEP2</u><u>;</u></h2>
CHANGE 20 MINS INTO HRS
1 hr = 60mins
<h2> x</h2>
? = 20mins
<u>2</u><u>0</u><u>m</u><u>i</u><u>n</u><u>s</u><u> </u><u>*</u><u> </u><u>1</u><u>h</u><u>r</u>= 1/3hr
60mins
<h2> <u>STEP3</u><u>;</u></h2>
Speed=distance÷time
90km/h= X ÷ 21/3
Distance= speed * time
X = 90km/h * 21/3hrs
<u>distance</u><u> </u><u>is</u><u> </u><u>2</u><u>1</u><u>0</u><u>k</u><u>m</u>
<h2><u>QN</u><u> </u><u>2</u><u>;</u></h2>
Speed=distance ÷
70km/h= X ÷ 21/3hrs
Distance=speed * time
X = 70km/h * 21/3hrs
