Question: John is 15 cm taller than Lena and 6 cm shorter than Rebeca. If John has a height of 152 cm, what is the height of Lena and Rebeca together? Think carefully first, then make a decision:
Lena is 152 cm - 15 cm = 137 cm tall. Rebeca is 152 cm + 6 cm = 158 cm tall. So, the total height of Lena and Rebeca would be 137 cm + 158 cm = 295 cm. So the answer is 295.
